Hello Since the last mail I sent I've managed to get our test client working and VPP running in a KVM VM.
We are still facing some problems though. We have a two servers, one where the virtual machines are running and one we use as the openstack controller. They are connected to each other with a 10G NIC. We have SR-IOV configured for the 10G NIC. So VPP is installed in a VM, and all interfaces work OK, then can be reached from outside the VM etc. Following the basic examples on the wiki, we configure VPP to take over the interfaces: vpp# set int ip address TenGigabitEthernet0/6/0 10.0.1.101/24 vpp# set int ip address TenGigabitEthernet0/7/0 10.0.2.101/24 vpp# set int state TenGigabitEthernet0/6/0 up vpp# set int state TenGigabitEthernet0/7/0 up But when trying to ping for example the physical NIC on the other server, we get no reply: vpp# ip probe 10.0.1.1 TenGigabitEthernet0/6/0 ip probe-neighbor: Resolution failed for 10.0.1.1 If I do a tcpdump on the physical interface when trying to ping, I see ARP packets being sent so -something- is happening, but it seems that packets are not correctly arriving to VPP... I can't ping from the physical host either, but the ARP cache is updated on the host when trying to ping from VPP. I've tried dumping counters etc. but I can't really see anything. The trace does not show anything either. This is the output from "show hardware": vpp# show hardware Name Idx Link Hardware TenGigabitEthernet0/6/0 1 up TenGigabitEthernet0/6/0 Ethernet address fa:16:3e:04:42:d1 Intel 82599 VF carrier up full duplex speed 10000 mtu 9216 rx queues 1, rx desc 1024, tx queues 1, tx desc 1024 tx frames ok 3 tx bytes ok 126 extended stats: tx good packets 3 tx good bytes 126 TenGigabitEthernet0/7/0 2 up TenGigabitEthernet0/7/0 Ethernet address fa:16:3e:f2:15:a5 Intel 82599 VF carrier up full duplex speed 10000 mtu 9216 rx queues 1, rx desc 1024, tx queues 1, tx desc 1024 I've tried a similar setup between two virtual box VM's and that worked OK, so I'm thinking it might have something to do with SR-IOV for some reason. I'm having a hard time troubleshooting this since I'm not sure how to check where the packets actually get lost... /Tomas
